Purpose/Abstract: Students are tested for their knowledge of basic titration technique and proper usage of specific-use probes (those used for conductivity, alkalinity, and pH, chloride, nitrate and hardness detection) on Logger Pro software. The purpose of this comprehensive lab is to determine the chemical properties of public drinking water found at four specific locations in the Toledo Ohio area. Students test the various properties of this drinking water by subjecting it to the following tests: pH tests, conductivity tests, total and phenolphthalein alkalinity tests, total hardness, chloride tests, and nitrates tests. With respect to the data collected in this lab, students also use conversion factors to calculate the parts per million. Following directions carefully and prudently is crucial for the success of the experiment and as well to the fact that the testing will be finished during the lab period. Tests like these are perform daily by industrial water treatment plant in order to ensure the Toledo public’s drinking water is safe. These plants are required by government agencies such the EPA to report its findings within a written deadline. Obviously reports of water quality that are not up to the government’s standards, (all of the standards will be listed at a later section in the report) will be subjected to further testing and isolated from public access until the standards are met. This lab mimics the daily routines of employed chemists at these facilities on a smaller scale. Students that chose to enter such profession will be held responsible for using the techniques learned in this lab.
Safety Information: Most of the chemicals used in this lab are dangerous. Avoid bodily contact, ingestion or any type of spills.
Assume that all of the reagents used
